What is this song?

The video that MMO-Champ posted a couple days ago has a certain MoP song in it and I can't figure out for the life of me what it is. I can't post the link of the video since I only have a few posts, but it's the video showing off the new Brawler's Guild Mushan mount. I checked the whole MoP soundtrack and it isn't on there. Does anyone know what song this is?

At the start it's the song played in the Forgotten Depths part of the Throne of Thunder raid.
The main track the plays (the wooden instrument with the air instrument) is Valley of the Four Winds' main song.
